The treaty of versailles was the representative of the end of World War I. However, this treaty of versailles was unfair to Germany, just because Germany was the lost country after WWI. Also, this treaty of versailles was for victory countries that won WWI, and they force the losers to sign up for this treaty. Furthermore, they kind of pay a lot attention in forcing them to observe the rules.
During world war 1, Germany lost the war, and they sign a contract with winners which is France, UK, and USA. Therefore, the conflict was coming. Hitler was an awesome guy who joined the military in Germany but he actually born in Austria, that was part of Germany before though. And he's pretty smart and became the leader of German's military and leading German fight again and so that cause the WW2 later, because he didn't agree with the treaty. One more thing that after they signed the treaty, the winners controlled their economy, and financial stuffs such as block their diplomacy with other countries.
Assume that I'm a german, I was living in Germany as a military, I won't follow or observe the rules with that treaty. The treaty that was showing us it was peaceful though, but actually the fact was unfair, and compellent. Thus, I would give my favor either join into the military fight with Hitler or work with German financial business that helps to improve the economy issues. I won't let other people belittle our own nation and block the way to strengthen our economy. At least, I might regard as an enemy to show our rage to other countries that we are not that strong. Although Gremany always dalay to observe the treaty, but they gonna fight though. So, that's what my thought of reaction as assume that I'm a German.
